Limited options for low-global-warming-potential refrigerants

February 17, 2017
Author(s)
Mark O. McLinden, J S. Brown, Riccardo Brignoli, Andrei F. Kazakov, Piotr A. Domanski
Hydrofluorocarbons, currently used as refrigerants in air-conditioning systems, are potent greenhouse gases, and their contribution to climate change is projected to increase. Future use of the hydrofluorocarbons will be phased down and, thus, replacement

Optimized Air-to-Refrigerant Heat Exchanger With Low-GWP Refrigerants

August 20, 2016
Author(s)
Piotr A. Domanski, Hong Hyun Cho
This paper presents an analytical evaluation of the performance of low-GWP refrigerants in a finned-tube evaporator used for residential cooling applications. The study employed an evolutionary-computation optimization module to examine the effect of a

Transition to Low-GWP Refrigerants: Options and Tradeoffs

April 6, 2016

Piotr A. Domanski
Hydrofluorocarbons (HFCs), which are commonly used as refrigerants in air-conditioning equipment, are potent greenhouse gases and will need to be replaced. In search of suitable replacements, a recent study performed a comprehensive screening of a database

Effect of Common Faults on the Performance of Different Vapor Compression Systems

December 31, 2015
Author(s)
Zhimin Du, Piotr A. Domanski, William V. Payne
The effect of faults on cooling capacity, COP, sensible heat ratio, and superheat/subcooling temperatures in five split and rooftop systems, which use different types of expansion devices, compressors and refrigerants, are separately compared and analyzed

Hitting the bounds of chemistry: Limits and tradeoffs for low-GWP refrigerants.

August 19, 2015

Mark O. McLinden, J. Steven Brown, Andrei F. Kazakov, Piotr A. Domanski
We explore the possibilities for low-GWP refrigerants through two approaches. First, we explore the performance of hypothetical refrigerants to define the limits of what is allowed by thermodynamics. In the second approach, we apply property estimation

EFFECT OF INSTALLATION FAULTS ON THE PERFORMANCE OF A SPLIT AIR CONDITIONER

August 18, 2015
Author(s)
Piotr A. Domanski, Hugh Henderson, William V. Payne
The study analyzed the effect of common installation faults on the cooling performance of a residential, split air conditioner installed in a single-family, slab-on-grade house. We considered five climatic regions in the United States from hot/humid to
